Here in germany shooting pb's is very restricted, so it was the only way to get into the shooting sport. I like the precision of airguns, i shooted pb on our local "Schützenverein" but it has not the meditating thing from shooting an airgun in your backyard (lucky i'm have nearly 40 yards range in my garden, most german guys don't have so much space).
I love the fact that i can shoot half inch groups on 40 yards with my "cheap" Diana trailscout, its so much fun.
Hitting cans or my little texas star is just amazing, while breathing fresh air and hearing the birds singing.
